KP127XFC series
KP127XFC Low Harmonic, High Power Factor Buck LED Driver Power Switch The KP127XFC is a highly integrated constant current LED power switch. The chip adopts a quasi-resonant operation mode, combined with active power factor correction control technology, to meet the requirements of high power factor, low harmonic distortion, and high efficiency. The KP127XFC integrates a high-voltage 500V power MOSFET and a high-voltage power supply circuit, simplifying system design and production costs. Through its unique constant current control algorithm, the chip can achieve high-precision constant current output, with excellent line voltage and load regulation. The KP127XFC integrates comprehensive protection functions to ensure safe and reliable system operation, such as: cycle-by-cycle current limit (OCP), over-temperature protection (OTP), output over-voltage protection (OVP), LED open circuit and short circuit protection, etc.
